A dynamic subwavelength pitch grating modulator for continuous Time-Of-Flight ranging with optical mixing

Since continuous Time-Of-Flight ranging systems based on electrical mixing run into fundamental limits we designed an optical MEMS (de)modulator/mixer. With our dynamic (MHz range) subwavelength pitch diffraction grating we demonstrated TOF ranging with optical mixing
